The present disclosure relates to transmission methods and devices inwireless communication systems, and in particular to a method and deviceof radio signal transmission in a wireless communication system thatsupport cellular networks.

Related Art

In a 5G system, in order to support more demanding Ultra Reliable andLow Latency Communication (URLLC) traffic, for example, with higherreliability (e.g., a target BLER of 10{circumflex over ( )}-6) or withlower latency (e.g., 0.5-1 ms), a study item (SI) of New Radio (NR)URLLC advancement was approved at the 3rd Generation Partner Project(3GPP) Radio Access Network (RAN) #80 Plenary. And the 3GPP has alsoagreed upon introducing data transmissions and Uplink ControlInformation (UCI) feedbacks of different priorities in URLLC with a viewto supporting higher reliability and lower latency requested by URLLCtraffics.

SUMMARY

In NR URLLC, the system efficiency can be enhanced by multiplexing UCIfeedback of High Priority and UCI feedback of Low Priority (especiallyHybrid Automatic Repeat reQuest (HARQ) feedback) on a same channel, suchas a Physical Uplink Control CHannel (PUCCH). However, due to variedproperties of UCI of different priorities, how to multiplex two UCIfeedbacks in a reasonable way remains a problem to be solved.

To address the above problem, the present disclosure provides asolution. It should be noted that though the present disclosure onlytook the NR URLLC scenario for example in the statement above, it isalso applicable to other scenarios confronting the same difficulty,where similar technical effects can be achieved. If no conflict isincurred, embodiments in any node in the present disclosure and thecharacteristics of the embodiments are also applicable to another node.What's more, the embodiments in the present disclosure and thecharacteristics in the embodiments can be arbitrarily combined if thereis no conflict.

Embodiment 4

Embodiment 4 illustrates a schematic diagram of a first communicationdevice and a second communication device according to the presentdisclosure, as shown in FIG. 4 . FIG. 4 is a block diagram of a firstcommunication device 410 and a second communication device 450 incommunication with each other in an access network.

The first communication device 410 comprises a controller/processor 475,a memory 476, a receiving processor 470, a transmitting processor 416, amulti-antenna receiving processor 472, a multi-antenna transmittingprocessor 471, a transmitter/receiver 418 and antenna 420.

The second communication device 450 comprises a controller/processor459, a memory 460, a data source 467, a transmitting processor 468, areceiving processor 456, a multi-antenna transmitting processor 457, amulti-antenna receiving processor 458, a transmitter/receiver 454 and anantenna 452.

In a transmission from the first communication device 410 to the secondcommunication device 450, at the first communication device 410, ahigher layer packet from a core network is provided to thecontroller/processor 475. The controller/processor 475 implements thefunctionality of the L2 layer. In DL, the controller/processor 475provides header compression, encryption, packet segmentation andreordering, and multiplexing between a logical channel and a transportchannel, and radio resource allocation of the second communicationdevice 450 based on various priorities. The controller/processor 475 isalso in charge of HARQ operation, a retransmission of a lost packet anda signaling to the second communication device 450. The transmittingprocessor 416 and the multi-antenna transmitting processor 471 performvarious signal processing functions used for the L1 layer (i.e., PHY).The transmitting processor 416 performs coding and interleaving so as toensure a Forward Error Correction (FEC) at the second communicationdevice 450 side and constellation mapping according to each modulationscheme (i.e., BPSK, QPSK, M-PSK, and M-QAM, etc.). The multi-antennatransmitting processor 471 performs digital spatial precoding, whichincludes precoding based on codebook and precoding based onnon-codebook, and beamforming processing on encoded and modulatedsignals to generate one or more parallel streams. The transmittingprocessor 416 then maps each parallel stream into a subcarrier. Themapped symbols are multiplexed with a reference signal (i.e., pilotfrequency) in time domain and/or frequency domain, and then they areassembled through Inverse Fast Fourier Transform (IFFT) to generate aphysical channel carrying time-domain multicarrier symbol streams. Afterthat the multi-antenna transmitting processor 471 performs transmissionanalog precoding/beamforming on the time-domain multicarrier symbolstreams. Each transmitter 418 converts a baseband multicarrier symbolstream provided by the multi-antenna transmitting processor 471 into aradio frequency (RF) stream, which is later provided to differentantennas 420.

In a transmission from the first communication device 410 to the secondcommunication device 450, at the second communication device 450, eachreceiver 454 receives a signal via a corresponding antenna 452.

Each receiver 454 recovers information modulated to the RF carrier, andconverts the radio frequency stream into a baseband multicarrier symbolstream to be provided to the receiving processor 456. The receivingprocessor 456 and the multi-antenna receiving processor 458 performsignal processing functions of the L1 layer. The multi-antenna receivingprocessor 458 performs reception analog precoding/beamforming on abaseband multicarrier symbol stream provided by the receiver 454. Thereceiving processor 456 converts the processed baseband multicarriersymbol stream from time domain into frequency domain using FFT. Infrequency domain, a physical layer data signal and a reference signalare de-multiplexed by the receiving processor 456, wherein the referencesignal is used for channel estimation, while the data signal issubjected to multi-antenna detection in the multi-antenna receivingprocessor 458 to recover any second communication device 450-targetedparallel stream. Symbols on each parallel stream are demodulated andrecovered in the receiving processor 456 to generate a soft decision.Then the receiving processor 456 decodes and de-interleaves the softdecision to recover the higher-layer data and control signal transmittedby the first communication device 410 on the physical channel. Next, thehigher-layer data and control signal are provided to thecontroller/processor 459. The controller/processor 459 performsfunctions of the L2 layer. The controller/processor 459 can beassociated with a memory 460 that stores program code and data. Thememory 460 can be called a computer readable medium. In DL, thecontroller/processor 459 provides demultiplexing between a transportchannel and a logical channel, packet reassembling, decrypting, headerdecompression and control signal processing so as to recover ahigher-layer packet from the core network. The higher-layer packet islater provided to all protocol layers above the L2 layer, or variouscontrol signals can be provided to the L3 layer for processing. Thecontroller/processor 459 is also in charge of error detection employingACK and/or NACK protocols so as to support HARQ operation.

In a transmission from the second communication device 450 to the firstcommunication device 410, at the second communication device 450, thedata source 467 is configured to provide a higher-layer packet to thecontroller/processor 459. The data source 467 represents all protocollayers above the L2 layer. Similar to a transmitting function of thefirst communication device 410 described in DL, the controller/processor459 performs header compression, encryption, packet segmentation andreordering, and multiplexing between a logical channel and a transportchannel based on radio resource allocation of the first communicationdevice 410 so as to provide the L2 layer functions used for the userplane and the control plane. The controller/processor 459 is alsoresponsible for HARQ operation, a retransmission of a lost packet, and asignaling to the first communication device 410. The transmittingprocessor 468 performs modulation and mapping, as well as channelcoding, and the multi-antenna transmitting processor 457 performsdigital multi-antenna spatial precoding, including precoding based oncodebook and precoding based on non-codebook, and beamforming. Thetransmitting processor 468 then modulates generated parallel streamsinto multicarrier/single-carrier symbol streams. The modulated symbolstreams, after being subjected to analog precoding/beamforming in themulti-antenna transmitting processor 457, are provided from thetransmitter 454 to each antenna 452. Each transmitter 454 first convertsa baseband symbol stream provided by the multi-antenna transmittingprocessor 457 into a radio frequency symbol stream, and then providesthe radio frequency symbol stream to the antenna 452.

In a transmission from the second communication device 450 to the firstcommunication device 410, the function of the first communication device410 is similar to the receiving function of the second communicationdevice 450 described in the transmission from the first communicationdevice 410 to the second communication device 450. Each receiver 418receives a radio frequency signal via a corresponding antenna 420,converts the received radio frequency signal into a baseband signal, andprovides the baseband signal to the multi-antenna receiving processor472 and the receiving processor 470. The receiving processor 470 and themulti-antenna receiving processor 472 jointly provide functions of theL1 layer. The controller/processor 475 provides functions of the L2layer. The controller/processor 475 can be associated with the memory476 that stores program code and data. The memory 476 can be called acomputer readable medium. The controller/processor 475 providesde-multiplexing between a transport channel and a logical channel,packet reassembling, decrypting, header decompression, control signalprocessing so as to recover a higher-layer packet from the secondcommunication device 450. The higher-layer packet coming from thecontroller/processor 475 may be provided to the core network.
